Two frequently-asked questions about bikes:

1. I heard the City of Chicago auctions off unclaimed and abandoned bikes. Where can I find information about these auctions? The auctions are managed by Ace Auctioneers and include bicycles as well as other merchandise. All merchandise is sold as is and on a cash-only basis. You can visit the Ace Auctioneers website, www.aceauctioneers.com, for the auction schedule and location. If you have questions not answered on the website, call Ace at 773.583.3111 and leave a message.

2. I locked my bike to a bike rack (or parking meter, sign post, etc.) yesterday evening, and when I came for it this morning it was gone. Could the City have removed it, or was it stolen? Unfortunately, it was probably stolen. Before the City removes a bike, it attaches a placard to the bike indicating its intention to remove it. The removal is not done for at least seven days, to give the owner ample time to move the bike or at least to contact Bike Program staff. Therefore, if your bike disappears overnight or in just a few days, it was not removed by the City. In that case, we recommend you call 311 to report it stolen. If you registered your bike, it increases the chances that we can recover it.
